Grin

Have you ever uncontrollably grinned?

It's common to find yourself laughing or smiling around others, especially when they seem to have a particular sense of humor.

But to uncontrollably grin when you're all alone:

When you're reading a letter, a note, something... meant for YOU.

(And this is PRECISELY where you'd find that person starting to grin.)

ISN'T THAT REALLY a notable sensation: One I never realized was so sweet until now.

It's notable not because you're grinning, but because you're smiling all on your own: Because you're genuinely, uncontrollably happy. Maybe it's because you've been remembered, because you feel connected, because you suddenly feel at peace.

But it doesn't matter how or why because you're breathing, and those moments make you happy.
